A porter lifts a luggage of 15kg from the ground and puts on his head 1.5m above the ground.Calculate the work done by him on the luggage.
The formula for work, as we know, is Work = Mass x Gravity x Height. Here, the mass of the luggage is 15 kg, the constant of gravity is 10 m/s^2, and the height is 1.5 m. Therefore, the total amount of work done can be calculated by multiplying these three values, that is, Work= 15 x 10 x 1.5 = 225 Joules
